Application method of Cotton Seedling Preservation Agent

First, the use of cotton seedling protection agent cotton seedling protection agent by large, medium and small three bags, the specific seed soaking steps are: 1, 5 kg of cotton seeds with three-pack (about 70 ℃) a cool water soaking for 5 minutes, the cotton seeds out, squeeze out the excess water. 2. Dissolve the small bag of reagent in 0.5 kg of water, into the cotton soaked in cool water, pour and stir until fully stirred for 24 hours (2 or 3 times in the middle). 3. Dissolve the medium bag reagent in 1.54 kg of water, pour it into the cotton seed soaked by the small bag reagent, stir fully and place for 24 hours. 4. Dissolve the large bag of reagent in 1.5 kg of water, pour it into the cotton seed soaked by the medium bag of reagent, stir fully and place for 24 hours. After treatment, you can sow seeds, or put them in a wet bag to accelerate germination and sow seeds. When the mountain merchants sow seeds, the soaking time of each bag can be shortened to 12 hours. Or soak 10 kg cotton seeds in cold water for 12 hours, remove and control water, dissolve the large, medium and small bags of reagents in 2 kg water, put them into the cotton seeds soaked in cold water, stir fully and place them for 12 hours to accelerate germination and sow seeds.

Second, matters needing attention 1. The process of cotton seed treatment by protecting cotton seedlings is a process of resistance training of cotton seeds. It is to let the cotton seed fully absorb the reagent into the cotton seed, so as to reduce the invasion of soil salt ions and bacteria, and improve the stress resistance of cotton seedlings, with a long aftereffect. However, the effect of shortening the time of soaking seeds or soaking seeds once is not as good as putting them for 24 hours each time. 2. When the cotton seeds are delinked with sulfuric acid or need to be sowed by machine, the seeds can be soaked directly with cotton seedling protection agent instead of soaking the seeds with three cuttings and one cool. However, the amount of water added in the three bags of reagent is 1.8 kg, and the seed soaking is 6 kg. The other steps are the same. 3. When cotton seedling preservative and pest control pesticides are used at the same time, after soaking the seeds for three times, mix the pesticide before sowing. 4. After soaking seeds with cotton seedling protection agent, if cotton seeds are wet and unsuitable for sowing, you can blow or bask in the wind for a while, but do not let the seeds lose too much water, otherwise it will affect the effect. 5. When soaking seeds, if the weather is dry and the seeds lose water quickly, the seeds can be covered with a wet cloth; if the temperature is on the high side (the daily average temperature is more than 20 ℃), the soaking time can be appropriately shortened to avoid longer seed germination affecting sowing.
